ILO 3 and ILO 4 TLS settings

Hi there,

I was given a directive to move to support only TLS 1.2 and above on all our ILO's. We have ILOs 3 and 4.

I believe ILO 3 will not support TLS 1.2, so I'm looking for steps to disable tls 1.0 and enable tls 1.1. Also looking for the same instructions on how to change settings on ILO 4 to tls 1.2 only and disable the other two.

Greatly appreciate your input,

As far as I know, TLS configuration is not available in iLO interface.
TLS can be configured in IE settings and/or JAVA control panel.

Re: ILO 3 and ILO 4 TLS settings


There is no disable or enable option for ILO, these settings are firmware driven. Please refer to the ILO firmware revision history. 

ilo3 : 

disabled with firmware 1.88 - Disabled TLSv1.0 when the FIPS mode or Enforce AES/3DES Encryption options are enabled.

added with firmware 1.87 - Added TLS 1.1 support to .NET Integrated Remote Console.


ILO 4:

Enabled with firmware 2.44:

Security fixes/enhancements:

  • Modified "Enforce AES/3DES Encryption" setting to only allow TLS 1.2 protocol
